Answer:
Explanation:
Given
Electrostatic force between two electrons is equal to weight of one electron
i.e.
[tex]\frac{kq_1q_2}{r^2}=m_e\cdot g[/tex]
where [tex]q_1,q_2[/tex] are the charge of particles
[tex]m_e=[/tex]mass of electron
r=distance between them
[tex]\frac{9\times 10^{9}\times 1.6\times 10^{-19}\times 1.6\times 10^{-19}}{r^2}=9.11\times 10^{-31}\times 9.8[/tex]
[tex]r=5.08\ m[/tex]
